Dude, ever thought of seeing someone about compulsive behaviour?
Seriously, my one extravagance is my motorbike. I know it's pretty extravagant spending more on a toy than on a family car (don't even start on running costs!) but OMG, it's seventh heaven when I'm tearing over the mountain tops in the early morning sun in high summer. Just me and a blur of undulating winding tarmac. Hard to top that.
